Thanks for help, I did it about like this for starters and it seems to work.
On my C++ function:
Q_INVOKABLE QVariantMap readEntries(QString table)
...
QSqlQuery q = QSqlQuery("SELECT * FROM params ORDER BY parameter ASC", *db);
QVariantMap tmp;
if (q.exec())
while (q.next())
tmp.insert(q.record().value("parameter").toString(),
q.record().value("value").toString());
return tmp;
On my QML:
Component.onCompleted:
{
var tmp = logger.readEntries("parameters")
for (var par in tmp)
{
parameterListModel.append({"parameter": par, "value": tmp[par]})
}
}

Actually, that's the best solution so far. Just make sure you follow the
structure of the in qml/js of data inside QVariantList. Playing around QVariant
and *List is a bit tricky but once you get the hang of it, it's awesome
datatype.
thanks,Jarko

Hi,
Or if you don't want to subclass e.g. qabstractitemmodel, you can always return
a QVariantList(or QList) from c++ and expose that sequence to QML. Then use
that JS array to populate ListModel.

Hi,
I have done the same thing in my Sailfish learning project. It was way more
complicated than I would have liked it to be (or maybe I did it in the wrong
way...).
Feel free to have a look at how I implemented it:

The code quality is probably not the best - these are my first baby steps in QT
and Sailfish. ;)

Hi,,
Thank you Janne and Jarko, I will take a look on both of these approaches;
> use the QSqlQueryModel in your c++ and expose that to QML ; just like in :

> subclassing QAbstractItemModel. See

> http://qt-project.org/doc/qt-5/qabstractitemmodel.html to get started.
